Two more people were cleared overnight in Corangamite, leaving only one active case from a previous high of four.
The case numbers include one from outside the region.
The good news arrives as Warrnambool starts local vaccinated economy trials, opening four businesses to fully vaccinated people.
South West Healthcare CEO Craig Fraser said the high vaccination rate, reduction in case numbers and start of the trials were reasons for cautious optimism.
However, while praising the community for its response, Mr Fraser urged people to remain COVID-safe.
“We are now entering the next phase of our battle against COVID and while we’re in a good spot and people can start to move around, we must remember to be safe in everything we do,” Mr Fraser said.
“The new trial is a great opportunity for Warrnambool but we have to be aware the threat of COVID is never far away and maintain social distancing and hygiene protocols"
“Our high vaccination rate and the way the community has responded in getting tested and also in minimising movement during this most recent outbreak has allowed us to keep it under control and move into this trial, now we have to embrace a cautious re-opening.”
Mr Fraser said he expected the remaining active COVID case in Camperdown to be cleared this week.
Some people in Warrnambool are also approaching the end of their 14-day isolation period.
“We encourage them to keep doing the right thing which will help us to clear more cases, helping us to move closer to our aim of zero cases over the next seven to 10 days.”
Over the weekend, 650 people were tested in Warrnambool, bringing the weekly total to 2712, all tests returned so far were negative.
There were no new exposure sites identified over the weekend.
